Tutorial: Fundamentals of Transceivers for Communication and Sensing
G. Gramegna · 2024
Wireless communication and radar systems are ubiquitous, and integrating both together is an active recent area of research. This tutorial will cover the basics of wireless communication and FMCW/PMCW/OFDM radar, while adopting a unified language and approach to encompass both communication and sensing topics. The advantages and disadvantages of existing transceiver architectures and beamforming implementations for communication and sensing will be explained, while MIMO radar will be introduced and compared with a beamforming approach. A few building blocks common to communication and radar systems will be described. Finally, a communication implementation will be compared with several radar architectures to provide insights into the challenges of adding sensing functionality to a communication system.
